摘要

有机管理能促进独特而稳定的土壤微生物群落的形成，然而，有机管理对灭菌土壤微生物群落的时间恢复和多功能性的影响仍然知之甚少。我们使用扩增子测序法和元基因组测序法研究了长期有机和常规管理土壤中的微生物群落对恢复土壤微生物组和功能的影响。我们采用平均法计算了土壤在重新定殖 30 天和 90 天时的多功能性。结果表明，与常规管理（C）相比，有机管理（O）显著提高了微生物群落的α多样性、生态位宽度和网络复杂性。有机土壤悬浮液土壤中微生物群落的阿尔法多样性、生态位宽度和网络复杂性在重新定殖的第 30 天和第 90 天明显高于常规管理。接种了有机土壤悬浮剂（OO）的灭菌有机管理土壤的土壤多功能性比其他处理高出 14.6% 至 70.6%。宏基因组分析表明，与 C 相比，O 显著富集了 ABC 转运体、碳代谢、氨基酸生物合成、双组分和氮代谢的功能途径，以及碳降解、碳固定、氮循环和磷循环的大部分功能基因。此外，微生物组的α多样性、生态位宽度、网络复杂性、功能途径和功能基因与土壤多功能性呈正相关。综述与应用。我们的研究结果强调了有机管理引起的微生物群落多样性、网络复杂性和功能性变化对促进土壤微生物和功能损失恢复的重要性，为农艺生产中有机管理对土壤微生物组和功能的可持续影响提供了理论基础。在期刊博客上免费阅读本文的通俗摘要。

期刊介绍： Functional Ecology publishes high-impact papers that enable a mechanistic understanding of ecological pattern and process from the organismic to the ecosystem scale. Because of the multifaceted nature of this challenge, papers can be based on a wide range of approaches. Thus, manuscripts may vary from physiological, genetics, life-history, and behavioural perspectives for organismal studies to community and biogeochemical studies when the goal is to understand ecosystem and larger scale ecological phenomena. We believe that the diverse nature of our journal is a strength, not a weakness, and we are open-minded about the variety of data, research approaches and types of studies that we publish. Certain key areas will continue to be emphasized: studies that integrate genomics with ecology, studies that examine how key aspects of physiology (e.g., stress) impact the ecology of animals and plants, or vice versa, and how evolution shapes interactions among function and ecological traits. Ecology has increasingly moved towards the realization that organismal traits and activities are vital for understanding community dynamics and ecosystem processes, particularly in response to the rapid global changes occurring in earth’s environment, and Functional Ecology aims to publish such integrative papers.
